The Evil Within has an extended gameplay video available for you to watch below. In the game, detective Sebastien Castellanos and his partners are called in to investigate a mass murder, when a "mysterious force" slaughters Sebastian's fellow officers. Knocked unconscious, when he awakens, he finds his world "has been turned upside down." This is where the video opens.
The Evil Within is in development for the Xbox One, Xbox 360, PlayStation 4, PlayStation 3, and PC and is slated for release in 2014.
